I'm not able to retrieve any custom fields on the Task object. I'm able to get Contact custom fields fine. These fields are included in a managed package, but I don't understand why the Contact fields are coming over fine, but not the Task fields. Below is the task object and field reference in the build file.
After trying to manually add the fields to the build file, I recieve an error "Entity Enumeration Or ID: bad value for restricted picklist field: Task
Any ideas? Thanks
